wow whatta beast. looking under the hood!!! WOW!!!!
Dead cylinder.....wasn’t throwing a code, I knew it had a something going on. Turns out it wasn’t just the carb, and then wasn’t just the tune. Swapped coils, wires, plugs, going to swap around some injectors next. May come down to a stick lifter or valve unfortunately. With the big cam it’s not easy to find, only missing under a load
Mine started running like shit a while back. I just had the chance to look at it today after being gone for 12 weeks. I started tugging on wires and got the f shocked out of me when the coil wire fell off.Just bad ground issue. Tip for LS swaps. You can never have enough grounds
Problem solved
It’s nice when it’s easy.
Needs a blower!

Been fighting a miss off and on. I’ve done everything I can think of other than valvetrain. Maybe a lifter sticking? Either way I ended up buying back a LQ4 that I put together. Going to swap it in instead of pulling this 5.3 apart. 
When in doubt, swap it out!
Put some time in on the el Camino LS swap yesterday so today was free for the truck. Pulled the overly cammed 5.3 out and put in a stock 6.0 that I had gone though the top end on. Motor has new gaskets a few things. Still tempted to put a BTR torque cam in it 
Here’s the plugs I pulled out of 5.3. They had one trip to town in them. 50 miles tops.

What’s up with the el Camino project. Didn’t see that one.
Don’t have a thread for it. It’s a side project for a friend. Pulled the LS1/T56 out of this 99 Z28 camaro. Swapped it into the 73 El Camino

Not saying that the elco doesn't deserve a decent second life with a ls1/t56. But that Camaro doesn't look like swap material either...
It wasn’t. Sad day for the 99 HO Z28. It may live again

Dislike.
So as soon as I read about this new Brian Tooley cam I knew I needed it. Got one of them coming, a new fuel tank, and also an aluminum radiator to move that top hose to the passenger side!
